Hi, I have an image, I crop it, add some text to the photo, then I want to save that photo into a cell

imshow(CroppedImage)
text(10,10,text_for_pic,'Color','y')

I have this running within a loop of a large set of images and then concatenate the images (stitching)

AA=ImageCell{:};
ImageCell = cat(2,ImageCell{:}) ;

Any ideas for how I can save the croppedImage with the text on without using Computer Vision Toolbox?

If you have the Computer Vision Toolbox, you can insert your text into the image with InsertText otherwise you have to convert the displayed figure into an image which is a right pain and usually result in an image of a different size than you started with.

Hi, Yes I can't justify the purchase of that toolbox, shame as it would just be one line of code. At the moment I've saved each cropped image and then will have to record the whitespace off them.

Then you're stuck with getframe or print and all the issues that come with them. I don't use them so can't help. There may be a utility on the file exchange that would help.
